Review on Hoodman Steel 2000X UHS II Memory by Matthew Nielsen

Robust high-performance card. Unlike the Sony M series, they are actually close to their specs. (2) The Sony M cards I bought first were measured at only 40 MB/s on the same PC and in the reader! I'm willing to think that an older AMD processor might not give a 100 percent score. Got these for my new Lumix G9 with UHS-ii slots, works great. When shooting continuously at 20 fps, I need to clear the buffer quickly.
